Emergency recovery tapes allow you to restore your system and its data to the configuration stored on the media. To create emergency recovery tapes:
The number of tapes needed varies according to the size and configuration of your system.
If other users are listed, bring the system to single-user
mode with this command:
shutdown -y -g300 -i1
The -g300 flag in this command allows users 5 minutes (300 seconds) to close their files and log out. A broadcast message from root provides warnings that the system is coming down.
The -e option tells emergency_rec to back up the entire primary hard disk.
tape is the tape drive location of your inserted tape (ctape1 or ctape2).
tapesize is the size of the tape specified either as a number of 512-byte blocks or as a number with a suffix of k, M or G to indicate kilobytes, megabytes or gigabytes. For example, a tapesize of 512000 or 250M would indicate that the tape can hold 250MB of data. If the hard disk is larger than the capacity of a single tape, you are prompted to insert additional tapes as needed.
Wait for this command to finish processing
and then go to Step 7.
Enter:
/sbin/emergency_rec tape
tape is the tape drive location of your inserted tape (ctape1 or ctape2).
The emergency_rec command (without the -e option) backs up:
To back up these filesystems and volumes, see ``After creating emergency recovery tapes''.
